Windows Socket compatibility

Hi, what to do when I want to run my program both under W2k and W98 ??? Do I only need to recompile it under each OS ? I compiled my program under W2k, so under this OS it works well. But when I started it under W98, it crashed...I thought Windows Socket code is totally compatible...Thx.

WinSock is compatible on my machine under both OS. You will have to post the code.
